Achieving a Reversible and Durable Zn Anode Using the Polyzwitterionic Hydrogel Electrolyte for Efficient Zn-Ion Energy Storage

Achieving reversible Zn chemistry by constructing a built-in internal electric field to dynamically eliminate local charge accumulation

“…As illustrated in Fig. 2i, 30,39–43 the employment of the CP coating enabled satisfactory cycling stability of Zn in ZnSO 4 , superior to most recently reported ZIBs. It was concluded that the synergistic effect of cations and anions in CP boosts the reversibility of Zn by constructing a dynamic polarized electric field that effectively inhibits inhomogeneous Zn 2+ distribution and dendritic Zn growth.…”
